share authorization certification mechanism, dpos for short, is similar to the voting of the board of directors. The coin holders cast a certain number of nodes to verify and account on their behalf. In order to encourage more people to participate in the election, the system will generate a small amount of tokens as a reward. Bitstocks, diandianbi and other digital assets use this method
dpos is a bit like the parliamentary system or the people's Congress system. If representatives can't perform their ties, for example, when it's their turn to keep accounts, they will be removed and the network will select new nodes to replace them
each client of dpos has the ability to decide which nodes can be trusted. Compared with pow (workload proof mechanism), dpos greatly improves the ability of blockchain to process data, and can even achieve second arrival. At the same time, it also greatly reces the cost of maintaining blockchain network security, so that the transaction speed of digital assets is close to that of centralized settlement systems such as visa.
Mining bitcoin is also called mining. Starting from the essence of bitcoin, the essence of bitcoin is actually a special solution generated by a bunch of complex algorithms. A special solution is one of the infinite (in fact, bitcoin is finite) solutions that can be obtained from the equations. Every particular solution can solve the equation and is unique
in the metaphor of RMB, bitcoin is the serial number of RMB. If you know the serial number of a note, you have the note. The process of mining is to constantly seek the special solution of this equation system through a huge amount of calculation. This equation system is designed to have only 21 million special solutions, so the upper limit of bitcoin is 21 million
bitcoin: also known as "bitcoin", is a kind of network virtual currency. Internet users can use bitcoin to buy some virtual goods, such as clothes, hats, equipment, etc. in online games. Internet users can also use bitcoin to buy real goods
extended data:
shortcomings
first, the vulnerability of trading platform. The bitcoin network is robust, but the bitcoin trading platform is fragile. Trading platform is usually a website, which will be attacked by hackers or shut down by competent authorities
Second, the transaction confirmation time is long. When bitcoin wallet is first installed, it will consume a lot of time to download historical transaction data blocks. While bitcoin transaction, in order to confirm the accuracy of data, it will take some time to interact with P2P network, and the transaction will be completed only after the whole network is confirmed Thirdly, the price fluctuates greatly. Due to the intervention of a large number of speculators, the price of bitcoin for cash fluctuates like a roller coaster. Making bitcoin more suitable for speculation rather than anonymous trading Fourthly, the public did not understand the principle, and the traditional financial practitioners resisted. Active netizens understand the principle of P2P network and know that bitcoin has no legal person to manipulate and control. But the public doesn't understand, and many people can't even tell the difference between bitcoin and q-coin“ "No issuer" is the advantage of bitcoin, but in the view of traditional financial practitioners, "no issuer" currency is worthlessWhy do I say that blockchain technology will change the future of social e-commerce
I. what problems have blockchain technology solved?
"recently, people often ask me that blockchain makes money, but can you tell me in one sentence what problems blockchain technology has solved?"
although many people know that blockchain technology supports the operation of bitcoin, many people in the circle are speechless when it comes to what problems have been solved or what value blockchain has created. Because of the super high profit making effect, we can't calmly view the instry or even the so-called ecology from the perspective of investment or technology
recently, I got a better answer when I interviewed some "coin circle old people"
"blockchain technology is the first time in human history to solve the problem of trust between people through technical means."
through the characteristics of blockchain, we can make it completely tamperable, traceable, and trade through smart contracts. Therefore, in theory, all those who need to solve the problem of trust between people through technical means need blockchain technology for development and innovation
Second, in the Internet era, social networking and e-commerce are born. Internet is a problem that human beings greatly optimize information transmission through technical means. In the Internet era, the business model is roughly divided into three moles: advertising, e-commerce and games. Therefore, in the Internet era, the rise of e-commerce and social networking is beyond doubt P>takes the highly competitive electricity supplier instry today. Alibaba and Jingdong are the best in the field of electricity supplier. The Chinese mainland electricity supplier instry has achieved the explosive development in the electricity business for 17 years in the Internet wave. Wechat, the largest social software in China and the second largest in the world, has also become the leader of the instry
after the baptism of time, the current Internet instry has formed an obvious oligopoly effect. Nowadays, every oligarch in the e-commerce market has become an important ship in the instry. Of course, it is also difficult for big ships to turn around. In this state. All the e-commerce companies are looking for new directions to break the situation. And many people are focused on the cross-border cooperation in the field of social e-commerce
the two representatives of social e-commerce are e-commerce carried in micro blog and wechat ecology. At present, the total market share of social e-commerce has reached as high as 14% - 20%
although many people say that the biggest application of blockchain is currency speculation, the initiation of projects like sec indicates that blockchain technology is possible to improve the current situation of the instry. It is precisely because there are many teams like sec, looking for the combination of technology and instry, and solving the key problems of the instry, that is the future research direction and consensus of the whole blockchain
